Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology and relates to an auxiliary replacement structure for equipment belts. Background Technology

[0002] The conventional method for adjusting a motor belt is to first loosen the fixing bolts of the motor base plate, and then adjust the bolts to move the motor base plate back and forth to replace the motor belt. Alternatively, the adjusting bolts can be used to move the tension wheel to replace the belt. After installation, the tension must be manually checked, and the fixing bolts should be tightened only after the tension meets the standard.

[0003] The disadvantages of the existing technology are that both methods are manual adjustments, which are time-consuming and labor-intensive, and cannot guarantee that the tightness of each adjustment is consistent. This can easily lead to increased wear on the motor bearings, belts and pulleys, and may even cause the motor to burn out. Summary of the Invention

[0021] Due to the angle of the drawing, some parts may not be drawn, but their positions and connections can be understood from the text descriptions.

[0022] like Figure 1 As shown, this utility model is an automatic motor belt tension adjustment device, including a base 1, which is rotatably connected to a motor base plate 2 via a rotating shaft 8. A motor 3 is mounted on the motor base plate 2, and a pulley 10 is mounted on the output end of the motor 3. The pulley 10 is connected to a mechanical spindle 12 via a belt 11. The motor base plate 2 is driven by an adjusting cylinder 7, and a limiting mechanism and a locking mechanism are provided between the base 1 and the motor base plate 2.

[0023] like Figure 3 As shown, the base 1 has bearing mounting holes and a shaft through hole in sequence, the motor base plate 2 has connecting screw holes and a shaft positioning hole, and the shaft 8 has a bolt hole through the middle. The shaft 8 is located in the bearing mounting hole, the shaft through hole, and the shaft positioning hole. The shaft bolt 14 passes through the bolt hole and is screwed into the connecting screw hole. The head of the shaft bolt 14 abuts against the top of the shaft 8. A flat bearing 15 is placed in the bearing mounting hole. The upper outer circumference of the shaft 8 is threaded with a lock nut 13. The upper and lower ends of the flat bearing 15 abut against the lock nut 13 and the bottom of the bearing mounting hole, respectively.

[0024] In this embodiment, there are two pivot bolts 14.

[0025] The cylinder body of the adjusting cylinder 7 is hinged to the base 1, and the piston rod of the adjusting cylinder 7 is hinged to the motor base plate 2 through a pin, which drives the motor base plate 2 and the motor 3 to rotate around the rotating shaft 8.

[0026] The limiting mechanism includes limiting screws 5 and bolts 9. A limiting groove 2-1 is provided on the motor base plate 2, with one limiting screw 5 installed at each end of the groove 2-1. A bolt 9 is located within the groove 2-1, with the ends of the limiting screws 5 facing the bolt 9. When the adjusting cylinder 7 drives the motor base plate 2 and the limiting screws 5 to rotate around the shaft 8, the bolt 9 does not move. Therefore, when the limiting screws 5 and bolts 9 come into contact, the motor base plate 2 stops rotating.

[0027] The locking mechanism includes a bolt 9 and a locking cylinder 6. A cylinder mounting bracket 16 is connected to one side of the base 1. The cylinder mounting bracket 16 is hinged to the cylinder body of the locking cylinder 6 via a pin. The piston rod of the locking cylinder 6 is hinged to the end of the locking plate 4 via a pin. The locking plate 4 is threadedly connected to the end of the bolt 9. The middle of the bolt 9 is located in the limiting groove 2-1, and the head of the bolt 9 is located in the anti-rotation plate 17. The anti-rotation plate 17 is fixedly connected to the base 1. The anti-rotation plate 17 has an anti-rotation groove. The head of the bolt 9 is stuck in the anti-rotation groove, and the bolt 9 cannot rotate. Figure 2 As shown. The locking plate 4 is attached to the motor base plate 2.

[0028] The working process of this utility model is as follows: During normal operation, the locking plate 4 is tightly attached to the motor base plate 2, and the head of the bolt 9 is tightly attached to the base 1. The locking plate 4 and the bolt 9 fix the motor base plate 2 and the base 1. When the belt 11 needs to be replaced, the locking cylinder 6 is activated to move forward and loosen the bolt 9 and the locking plate 4, allowing the motor base plate 2 and the base 1 to move relative to each other. Then, the adjusting cylinder 7 is activated to push the motor base plate 2 forward and rotate it counterclockwise. When the bolt 9 contacts the limit screw 5, the belt 11 is in a loose state. After the worker removes and replaces the belt 11, the adjusting cylinder 7 is activated again to push the motor base plate 2 backward and rotate it clockwise. When the bolt 9 contacts the other limit screw 5, the belt 11 is in a taut state. At this time, the locking cylinder 6 is activated to move backward and lock the motor base plate 2, thus completing the entire belt replacement process.

[0029] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
